Why Replai is Different
We don't just translate code line-by-line. We recover lost metadata and build a semantic knowledge layer that captures the true business intent behind your legacy systems.
Traditional Black Box Tools
Line-by-line code translation
- •Directly converts old code to new syntax without understanding business logic
- •Creates technical debt by copying outdated patterns and inefficiencies
- •Locks you into a single target technology - inflexible and risky
- •Lost metadata remains lost - no recovery of business context or intent
Replai's Semantic Approach
Metadata recovery and knowledge modeling
- •Recovers lost metadata and builds a semantic knowledge layer of your entire system
- •Models business logic, workflows, and intent - not just code syntax
- •Rebuild in any architecture or technology stack - Java, .NET, cloud-native, or microservices
- •Future-proof your systems with complete flexibility and modern best practices
The Replai Advantage
Our semantic knowledge layer doesn't just preserve your legacy code—it reconstructs the decades of business knowledge and intent that have been buried inside it. This enables true modernization, not just translation, giving you the freedom to rebuild your systems the right way for today's architecture.
How It Works
Intelligent agents feed a living knowledge layer that powers all your capabilities
Recommendation Engine
AI-powered insights for optimization and modernization decisions
Unified Semantic Knowledge Layer
Connects every technical component to its business meaning
Multi-Agent Intelligence
Specialized agents continuously analyze your entire system
Source Code
Runtime
Dependencies
Business Logic
Metadata
Multiple specialized agents work together to continuously analyze, understand, and map your entire legacy system—feeding insights into the unified knowledge layer that powers intelligent exploration, optimization, extension, and modernization.
Uncovering the Lost Metadata
Everything you need to understand, analyze, and modernize your legacy systems
Understand & Assess Risk
Ask natural language questions about your legacy system — from business logic and workflows to potential risks in making changes. Gain instant insight into complex, critical code.
Analyze Component Logic
Dive into individual components to see triggers, field logic, and implementation details. Understand how each part functions before taking action.
Explore System Dependencies
Visualize your system with an interactive, searchable dependency graph. See relationships between components and get a responsive, focused view of the parts you care about most.
Modernize & Extend
Use AI-assisted coding to safely extend features, rebuild screens, or migrate legacy functionality (e.g., Oracle Forms → Oracle Apex), preserving underlying logic while enabling modernization.
Enterprise Use Cases
From understanding decades-old code to planning complete modernizations, Replai handles your most complex legacy challenges
